METHOD. FOR COOKING CATSUP AND. LIKE PRODUCTS To all whom it may c0'ncern.f p

Be it known that I, GEORGE R. Frnnns, a citizen of the United States, residing 111 Terra Haute, in the county of Vigo and whereby large quantities of stock may be A reduced and cooked without danger of burning, scorching or otherwise injuring the product, and, third, to furnish such a method, whereby catsup, or other like products, may be reduced andcooked in a sanitary, safe and economical manner.

These objects I attain by means of the method. hereinafter described, and the mechanism illustrated inthe accompanying drawings, in which, i

Figure 1 is an elevation: of the tank, shown partially in 880M011, to expose 1n- .terior. Fig. 2 is a plan of an apparatus suitable for carrying out my process.

Similar letters of reference refer to similar parts throughout the several views.

The apparatus necessarily used to cook catsup by my rocess consists of a large tank A, open at the top and provided with a floor, which is inclined from the back of the tank toward the front thereof, as shown in Fig. 1. The inclination of the fioor f is. an essential feature, in the construction of the apparatus and in the process, as more fully set forth hereinafter. A pair of large, ac1dproof, seamless tube coi1s,; G and C, one within the other, are erected within the tank A, and supported upon a plurality of metallic, acid-proof stays, or. standards S. The

standards Sare soldered firmly to the coils and all recesses between stays and coils are carefully filled with solder,or other suitable material, for the purpose of removing all possible danger of stock, or other material entering and lodging therein. All metal Specification of Letters Patent.

work isthoroughly tinned withpure tin, to prevent mpurities from forming, by reason of the acids in the stock. The coils O and C are connected at the upper, or intake eX- tremities, with steam supply-pipcs, P and P respectively, and the lower or discharge ex tremities of the coils are connected with discharge pipes, 72 and p which pass through the floor f of the tank A. The discharge pipes, 29 and p, are connected by a pipe g, which is furnished with a pendent drain valve 1". The connected discharge pipes have connection with an exhaustpipe ti One or: more suitable valves V, preferably of sliding stem type, are mounted upontheoutside of the tank A, in fluid-passage connection with corresponding discharge vents TV, one or more, of which are provided at the lowest possible point, or points, of the floor f, as shown in Fig. 1. The tank is mounted upon substantial supports X, of suflicient eleva tion to permit free passage of all discharge the supply-pipes P and P. .Tl1e steam so admitted follows the special course of the coils, therebyheating the coils, from which intense heat is diffused in all direct-ions throughout the bulk of pulp, in which the coils are immersed. Small quantities of cold water are dashed upon the cooking pulp to prevent foaming and a proper degree of heat is maintained for a proper length of time, tothoroughly reduce and cook the pulp to a finished catsup, or other like prod uct. The steam is then cut off from the to drain oil all condensation from the coils. The finished catsup is reduced to a, liquid condition and tends to. reach the lowest possible level, thereby forcing itself by gravitation to freely discharge through the discharge valve V, when the same is opened.

The advantages claimed for any process, as carried out by means of the apparatus described, consist; first, in the exceedingly large amount of stock which may be thoroughly cooked at one heat; second, in the absolute security against burning or scorching the catsup and the absence of danger supply-pipes and the drain-valve is opened from contamination from old stock, acids or other similar impurities, commonly experienced in the cooking of catsups, by other methods used prior hereto; and, third, in the increased degree of economy attained by reason of the economical construction and operation of the apparatus and the large saving in steam expense attained by reason of the improved manner of distributing and applying the heat. I

- When tomato catsup first b'oils, the coloring matter, which is lighter than the pulp rises to the top and unless some means is provided for checking the boiling over of the pulp, a large part ofthe natural coloring matter Will be lost. By spraying Water, or other suitable liquid over the pulp when the same is boiling, the natural coloring matter will be carried down into the pulp and also the boiling over Will be checked. In this Way the spraying of a cooling liquid upon the boiling pulp has the twofold result of checking boiling over of the pulp and retaining the natural coloring matter of said pulp.

I claim:

1. A process of cooking tomato catsup consisting in thoroughly pulping the stock, introducing the same into an open Wooden tank so that the same is under atmospheric pressure, introducing a diffusing heat into all parts of the stock from Withinthe tank, and spraying said stock when they coloring matter rises in said tank, with a cooling liquid.

2. The process of preventing the boiling over of catsup pulp and the escape of coloring matter contained therein Which consists in spraying the boiling pulp With a cooler liquid. 7 1
